Getting Raw RGB Data from an Android Camera

Question

I am working on a camera app on Android. I am currently taking my capture using jpeg callback. I would like to know if there is a way to get to raw capture data. I know there is a raw callback to capture, but it always returns null.

So, from jpeg callback I can access raw data (RGB pixel sequence).

EDIT:

So, from the jpeg callback, I can access the raw data (YUV pixel sequence).
